| Rotary instruments, piezoelectric osteotomes, and manual bone scrapers were used to perform the lateral antrostomy. |
|
| Considering the configuration of new bone formation, it was decided to perform the palatal antrostomy approach. |
|
| No perforation occurred during the antrostomy and the initial membrane elevation with piezoelectric inserts. |
|
| Sinus irrigation was conducted by lateral antrostomy through the canine fossa. |
|
| The most common surgical procedures included sphenoidectomy, ethmoidectomy, maxillary antrostomy, and middle turbinectomy. |
|
| We sought to quantify the effect of uncinectomy, small antrostomy, and large antrostomy on maxillary sinus ventilation using xenon-enhanced CT in the sheep model. |
|
| A major goal of maxillary antrostomy is to increase sinus ventilation. |
|
| Computed tomography of the sinuses showed evidence of the ethmoidectomy and a right middle meatal antrostomy in addition to left ethmoid opacification. |
